Deatschwerks DW300C O-ring spacer requirements?

Hi, I'm installing the DW300C, https://www.ftspeed.com/part/9-307-1...s#.XyaweyhKiUk

But getting conflicting information on the O ring and spacer requirements. Is it

- 3 O ring
- 4 O ring
- spacer + 1 O ring
- spacer + 2 O ring

Anyone can confirm on their own car what the right spec is?

I know this is a very old thread, you have 2 options. Either use 3 o-rings or 2 o-rings and the spacer. Start at 6:11
